SPECIFICATION forming part of Letters Patent No. 709,387, datedSeptember 16, 1902. Application led July 3, 1901. Serial No. 67,006. (Nomodel.)

To a/ZZ 1071/0711/ it muy' concern,.- Be it known that I, ERNEST BETZ, acitizen of the United States, and a resident of Washin gton, intheDistrict of Columbia, have made a certain new and useful InventioninHydrocarbon-Burners; and I declare the following to be a full, clear,and exact description of the same, such as will enable others skilled inthe artto which it appertains to make and use 1o the invention,reference being had to the ac.

companying drawings and to letters of reference marked thereon, whichform a part of this specification.

Figure l is a side elevation of my burner.

r 5 Fig. 2 is a perspective view of the burner with cap-plate G removed.Fig. `3 is a plan View of the burner. Fig. e is a partial vertical lon-`gitudinal section of the same. i The invention relates to hydrocarbon-burnzo ers, `and has for its object theprovision of a simpleand practical device of thisoharacter especially suited for burningkerosene-oil and arranged tojheat the oil to effectually convert it intovapor, also providing for the admixn ture of heated air with such vaporfor com-` plete combustion thereof toobtain a flame of T maximumcaloriic value."

A further object of the invention is to provide for such complete'combustion as will avoid the exhalation of odor from the burner.

y consists in the novel construction and combinations of parts, ashereinafter set forth.

`Referring to the accompanying` drawings,

the letter B designates the burner, and C the oil-feed pipe, suppliedfrom a suitable oil-res` chamber E, through which the extension of` theoil-feed pipe from the reservoir passes. This hot-air chamber isprovided with an airinlet in its bottom portion and with an airexit e inits top, such air-exit being laterally 5o arranged and provided with adeflector plate or ange e' above said opening to guide the `With theseobjects inview the invention The base-casting, 'usually (of rectangularor At the side of orA adjacent to the oily` rising heated air toward themixing-tube located adjacent thereto. At the opposite side of the base asimilar hot-air chamber having similar air inlet and exit passages isusually provided, as shown.

The mixing-tubes F are supported by small arms attached to the top ofthe base near the air-openingsin the top ofthe hot-air chamber.

From the oil receptacle or retort, being at- 6o tached thereto by meansof a threaded opening in itstop, extends the coil-pipe c, which isdisposed horizontally.above the base and, extending downward, isconnected to the burner-tube c', which extends under the mix- 65ing-tube and is provided with a burner-tip projecting upward into thesame.

`Above the base is a deflector-cap G, which is designed to be secured tothe base by means of attachment-lugs g therein being bolted to 7osimilar lugs of said base. This `cap G has small openings g2 g2 in itstop Wall and separated by the bridge-'bars g3, located directly above`the mixing-tubes to obstruct the direct draft immediately over thesame. The cap is designed to be provided with a downwardly and outwardlyinclined flange, which extends n nearlyito the top of the base, leavingan opening between its margin and said base, saiopeningbeingcontinuous,exceptat thepoin s 8o of attachment of the cap tothe base. This flanged cap practically incloses the coil-pipe and themixing-tubes and forms a dame-chamber of powerful heating capacity,whereby not only these parts are raised to high temi perature, but alsothe base including its closed oil-chamber and hot-air chambers areheated, the ,former sufficiently to vaporize the oil therein and thelatter to heat the draftair to the mixing-tubes. The margin of the 9odepending iiange of the cap is usually made et' wave-like contour inorder to subdivide the burning mixture of gas and air as it passesoutward thereunder, in this wise giving it a spreading character,whereby its flames rising exteriorly around the cap are designed toenvelop it, and thereby produce a mass of fire of very powerfulcharacter.

In operation, the valve of the oil-feed pipe being opened, the oil isallowed to pass into roo the oil-chamber E, wherein it rises through thecoil-pipe and passes out of the burnertips, falling upon the base-plate,where it is lighted. The burning oil lsoon heats up the burner-tips andcoil, vaporizng the oil therein, and the vapor mixed with air becomingignited heats up the parts further until the entire burner is raised toa high temperatu rev, vaporizing the oil in the oil-chamber, as well asin the coil-pipe. A continuous flame of powerful character is designedto be produced by the burner.

The heating capacity of the burnerl is such that it burns up all thevaporized oil, which escapes, and theodor which may exhale when thesupply is cut off is imperceptible.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- A l. In a hydrocarbon-burner, thecombination with the base, its oil-receptacle and hotair chamberbelowits top, the inclosing deflector-cap supported from said base, andhaving a depending flange extending downward nearly to said top, the'mixing-tube and coilpipe within said cap., the burner extension of saidcoil-pipe under said mixing-tube and above the top of said base-plate,and the oilfeed pipe extendingwithin thehot-air chamber to saidoil-receptacle., substantially as specified.

2. In a hydrocarbon-burner, the oil-receptacle and the adjacent hot-airchamber forming a base, the pipe from said receptacle, and itsburner-tip, on said base, the mixing-tube above said base, said chamberhaving air inlet and exit openings in its bottom and iop wallsrespectively, thev deflector-plate above 1 said exit-opening, and theoil-feed pipe passing through said hot-air chamber, substantially asspecified.

. 3. A hydrocarbon-burner, comprising the t base, its' oil-chamberand'adjacenthot-air chamber, the mixing-tube supported therefrom, thecoil-pipe from said oil-chamber extending to said mixing-tube, andprovided base of box `form divided by a partition to form anoil-receptacle and a hot-air chamber, the mixing-tube supported fromsaid base, the cap supported upon said base, and having a top, and adepending flange inclosing said tube and coil, and the oil-feedcoil-pipe extending from the oil-chamber upward between the base andcap, and downward under the mixing-tube, substantially as specilied.

5. A hydrocarbon-burner, comprising the base of box form divided by apartitionto form an oil-receptacle and a hot-air chamber,

Vthe mixing-tube supported from said base,

the oil-feed coil-pipe provided with a burnertip, the cap supported uponsaid base, and having a depending flange inclosing said eoil and tube,said flange being of such vertical extent as to leave only a narrowopening between its`margin and the base, and said hotair chamber having.air inlet and exit openings in its bottom and top walls respectively,substantially as specified.

In testimony whereof I aftix my signature in presence of two witnesses.
